SUMMARY
When adding a system tray using the "+" or "Add widgets..." button on an empty panel and simply clicking on the widget in the selection list instead of dragging it onto the panel, the system tray is added but remains invisible until the next login.

STEPS TO REPRODUCE
1. Create an empty panel.
2. Click on the "Add widgets..."/"+" button to open the widget selection.
3. Click on the System Tray widget (do not drag it onto the panel!)
4. Observe that the system tray is invisible.
5. Log out and log back in.
6. Observe that the system tray is now visible.

See https://youtu.be/OCOBXb8DzmI?si=5wObZ2cEkUPbSbKz for a video demonstrating the issue.

OBSERVED RESULT
The added system tray is invisible until the next login.

EXPECTED RESULT
The system tray should be visible immediately.

Thanks for the video; that's helpful. However I cannot reproduce the issue on git master with those steps, including making sure that the new empty panel is vertical.

Does it happen in a new clean user account on the same machine?

I'm also not able to reproduce the bug on git-master, or Plasma 6.3.5

I can reproduce it on an entirely separate Fedora 42 installation (also using the Plasma 6.4 Beta, of course) on the same machine with a clean user account. It also happens with the nouveau driver, so it doesn't seem to be specific to the proprietary NVIDIA driver.

I can't reproduce on a Fedora KDE 42 VM with Plasma 6.4.0, or on my Fedora KDE 42 desktop (NVIDIA proprietary graphics) with Plasma from git master.

If you open up a terminal and enter `sudo journalctl --follow`, and then reproduce this issue, could you let folks here know if there are any errors that show up?

Thanks!

I can't seem to reproduce the issue on Plasma 6.4 anymore (neither on my main installation nor the other one I had reproduced it on previously), so I guess it was fixed by some other change.

Comment 7 TraceyC 2025-06-23 22:22:51 UTC

Let's call this fixed in 6.4 then. If the issue happens again, feel free to set this report to REOPENED. Thanks!
